The idea for the dual-purpose vibe wasn't actually the original plan for the product. The tuning fork-looking gadget was designed with a USB port so it could be easily charged on the go in a computer or laptop. But when some savvy, multi-tasking users asked, "Can we store stuff on it, too?" the creators said, "Sure! Why not."

Let's be honest, though, convenience—and pleasure—comes at a price. Crave's Duet Lux 8 gigabyte vibe comes in at a whopping $219. Not the most affordable toy around, but if you use it for business purposes maybe you can get a tax write off?

If the Duet doesn't tickle your fancy, there are several other options out there for discrete playtime. Need some assistance "down there" in a pinch? Download the Closer ToGetHer app to turn your smartphone into an instrument of pleasure (beyond playing Temple Run). Those feeling a little more playful can pick up the I Rub My Duckie, a totally cute bathtub toy that doubles as a "vibrating body massager." It's all about multi-tasking, ladies.
